Application

ZMCF series reactive power automatic compensatingcontroller(hereinafter referred to as ZMCF)isapplicable for the automatic adjustment of capacitorcompensating device oflowvoltage distributionsystem, With power factor up to the user's presettingstate,it can improve the utilization eficiency ofelectric power transformer, reduce the wire loss andimprove the voltage quality.

Function characteristic

Calculate the capacitor capacitance by the fundamental wavereactive power, avoid the switching oscillation in any form.Correctly display the grid power factor under harmonic wave.High measurement accuracy of power factor, wide range of display.Real-time display of total power factor(PF).Real-time display of voltage distortion factor and current distortionfactor

Friendly human-machine interface, for convenient operationVarious control parameters, by digital display, very visual andconvenient to use

Two working modes: automatic and manualOver/under voltage protectionProtection against the impermissibly high voltage harmonic waveData is not lost due to the protection against the power failureLow input impendence of current signal: [0.01
